Discharge controlling device for faucets

Abstract

This invention is directed to a discharge controlling device for faucet, characterized in that a control lever is used to push a throttle pin axially positioned within the center of the housing, such that the pin is slidably moved up and down and engages a steel ball which is designed to control the opening and closing of a water discharge aperture. As the control lever is pushed by hand and moved from its lowest closed position to the intermediate, open position where the water can be admitted, the steel ball is pushed away from the aperture by the rod tip of the throttle pin which rises axially. At this instant, water enters through the aperture and flows out of the housing. When the hand is released from the control lever, the throttle pin will fall, and the steel ball, which is subject to water pressure, will immediately return to the position where it closes the aperture. As the control lever is moved manually from its lowest closed position to its fixed open position where it engages the locking slot, the control lever will be secured within the locking slot, and due to the locking effect of the slot, the aperture is kept open to allow continuous water flow even the hand is released. As the control lever disengages from the locking slot, the throttle pin drops and the steel ball, due to the action of water pressure, closes the aperture.

I claim: 
     
       1. A discharge controlling device for faucet comprising: a housing in which the upper end thereof being threaded to form the threaded edge, the intermediate portion thereof being embossed to form the embossed portion, the internal portion thereof having a space open at one end in which the upper end thereof being defined by a partition having a central aperture, a pair of locking slots being provided at the lower edge of the housing at two locations opposite to each other;   a throttle pin having a spherical surface at the lower end thereof, and an rod tip located at the upper end;   a control lever shaped to be a forked double spring plate;   a steel ball;   a seal ring, and   a diffusion ring having a central opening and a plurality of peripheral diffusion holes;   the seal ring being secured at the periphery of the housing aperture, the steel ball being positioned atop the aperture, the diffusion ring being placed within the interior space of the housing such that the lower edge thereof is above the upper edges of the locking slots located at the lower edges of the housing; the throttle pin being penetrated through the central opening of the diffusion ring, the control lever being locked with one end thereof secured within one of the locking slots, and the other end thereof secured within the other locking slot such that the throttle pin is carried by the control lever and positioned in place.   
     
     
       2. The discharge controlling device for faucet according to claim 1, wherein the aperture being stepped in configuration to form a recessed annular groove, and the seal ring being placed in the annular groove located around the periphery of the housing aperture. 
     
     
       3. The discharge controlling device for faucet according to claim 1, wherein the locking slots are open and extend through the lower edge of the housing, and include a locking neck each in the interior thereof to engage the control lever. 
     
     
       4. The discharge controlling device for faucet according to claim 1, wherein one end of the double spring plate of the control lever is formed into a head to facilitate the compressing of the spring plate and provide locking effect.
